Petunia Dursley

Her sister, Lily, may have been a witch but Petunia Dursley was a Muggle and staunchly anti-magic, more content to keep her home spick and span, and gossip about the neighbours. Despising anything with a hint of the wizarding world about it, she only very reluctantly took her nephew Harry Potter in when both of his parents were murdered. However, alongside her husband Vernon, she made sure Harry always felt unwelcome in their pristine home, while she spoiled her only son, Dudley, rotten.
